out of heap space when uploading large files

alanbell — Fri, 24 Dec 2010 10:36:48 GMT

I am using the python-cmis library to upload files to Alfresco community 3.4.b running on Ubuntu server.where /mnt/import/bigfile is a 298MB file. The file can be imported successfully using the share interface or classic Alfresco web UI and small files of a few MB in size are uploaded by this code

Hello

I am having a similar issue while upload a 100Mb file with Apache Chemistry CMIS library.
I am using the AtomPub protocol.

Here is the stack trace client side :

It looks like Alfresco tries to put the whole content in memory and it leads to a OutOfMemoryError.

The server is running with +/- 980Mb of memory

When I am using the SOAP protocol, everything just works file (I am able to upload really large files (1Gb+).

I would like to use the AtomPub protocol as it is less verbose, but this issue is blocking as the application will be uploading large files.

Any though on that ?

Hello Christophe,

did you find a solution to upload large files using Atompub protocol? I have the same problem using Alfresco Community 4.2
